Test Centre VUZ Velim
The Railway Research Institue, j.s.c. (VUZ) has at its disposal a unique testing and technological support facility. The complexity of service provided to the customers corresponds to the European standards.
The practical verification of technical parameters and running characteristics of railway rolling stock directly on the track belongs to the most effective modern testing methods. The VUZ in the Test Centre Velim operates two railway test rings, which are among the most important and the recognized test centres of railway technology and railway facilities in Europe. By its technical equipment it forms a unique compact unit to perform a number of runnig tests of rolling stock, railway equipment and transport means as well as other experiments and laboratory tests.

Tractive power systems of test tracks
The power supply system of the Test Centre Velim offers all major European tractive power systems.
- DC system 3 kV
- DC system 1,5 kV
- AC system 25 kV, 50 Hz
- AC system 15 kV, 16 2/3 Hz
- střídavou soustavu 15 kV, 16 2/3 Hz
Supplying the large and small test ring with the power separately is possible to allow different combinations of power supply.
3 kV System
- regulation from 0 to 4.0 kV
- permanent current 1.5 kA at 3 kV (4.5 MW)
- max. overload within 2 h – 2.1 kA
- recuperation – YES
25 kV, 50 Hz System
- regulation from 25 kV to 31 kV (9.75 MW)
- regulation from 16 kV to 25 kV (4.0 MW)
- permanent current 390 A at 25 kV (9.75 MW)
- recuperation – YES
15 kV, 16 2/3 Hz System
- regulation from 2.0 kV to 17.5 kV
- permanent current 533 A at 15 kV
- recuperation – YES
The test rings offer a possibility to perform all types of running tests.
Special offer consists in particular of:
- noise tests in the section of large test ring, parameters of which meet the requirements of technical specification of interoperability of the Rolling stock sub-system - noise
- tests of the European signalling and communication equipment ERTMS (ETCS, GSM-R) – test centre is covered by GSM-R signal and the section of large test ring is equipped by ETCS system
- possibility of simulation of changes and power supply disturbances including the eventual traction mains disturbances and the measuring of electric tractive unit response/li>
- EMC measuring in the section of large test ring specially equipped for this purpose
- Tests in the measured rail section created in the part of large test ring to exclude negative environ impact
The test center makes it possible to perform the stationary tests and vehicle revival in the auxiliary yard equipped with all the mentioned tractive power supply systems. The mentioned and other tests are offered by VUZ to be undertaken in co-operation with the accredited testing laboratory. In case of interest it will make it possible that the measuring be performed by their own means.
Test Preparation Halls
In the Test Centre Velim there are four Test Preparation Halls (HPZ) available. In addition halls HPZ II. and HPZ III. are new build and offer modern technology and facilities. More at the Test Preparation HallsDynamic testing laboratory
In the test centre there is a hall with a dynamic test bench. More on the dynamic testing laboratory
